i MACHINE FOR PRINTING FLOOR-CLOTH.

Specification of Letters Patent No. 8,778, dated March 2, 1852.

To all whom it 'may concern:

Be it kno-wn that I, SIMEON SAVAGE, of Lowell, in the county ofMiddlesex` and State of Massachusetts, have invented a new and useful orImproved Machine for Stamping and PrintingnPainted Floor-Cloth or`Carpets or other `Groods of Like Descrip# central, vertical, andlongitudinal section of` it, and exhibits the mechanism on one side ofsuch section. Fig. 5 is another and similar section and `exhibits the`machinery on the opposite side of the plane of section. Fig. 6 is aninner side view of `one o-f the gripper carriages and the grippingmechanism thereof.

In the said drawingsA represents a frame benchor table on which thepiece of` cloth to be printed in paint oroil color is to be laid, and onwhich itis tobe movedin order to be printed and stamped. i

B, and` O, are twoplatens; arranged directly over the top seurface ofthe bed A. One of the platens, wiz., the rst one, is to have theprinting figures, types, block, or blocks affixed to its under surface,and so that the printing surfaces shall be downward. The other or lastof the platens may have a plain surface, or it may have an impression orstamping-block afIiX-ed to its un-` der surface, the ob] ect` of thesaid platen being to stamp down the figure produced on the cloth by thetypes or figureblock, or printing surface of the other platen.

i To all or most of those acquainted with` the process of making paintedcarpets, it is well known thatthe oil paint or color is laid or printedonthe cloth in small drops or squares which stand on itseparate from oneanother, and with` spaces between them.

After my machine has `effected the imprinting process it also operatesto stamp down these spots or squares of color, or so comipress them asto extend each of themlaterally and horizontally in all directions so asto makethem run into one another or join togethefand thereby cover thespaces be-` tween `them and give tothe figure made by a collection ofsuch dots or squares. a unform colorwitho-ut breaks. My machine istherefore calculated not only to print in o-ne or more colors, accordingto the numlber o-f platens and coloring` apparatuses; but to stamp downand spread out the `color or colors after the application of the `sameto the cloth ormaterial to be printed.

, Having thus premised I would remark that besides the above mentionedprinting and stamping `down elements, my machine not only has acontrivance for holding and applying `the color to the printingsurfaces, but it possesses a mechanism for holding the sheet of cloth tobe printed, for carrying it forward at suitable times, and for retainingit under the printing and compressing platens, long enough for and so asto enable them to perform their respective oflices.

In the drawings D, exhibits the coloring trough or carriage whichcontains an elastic roller E, and is mounted on four wheels F, F, F,F,'Which rest and run on ways on the top surfaces of the timbers or barsa, b, of

the frame `or table A. `Within the fountain or colorftrough are one ormore gage bars c, CZ, which are so set near the curved surface of thecylindric roller as to regulate the thickness of the sheet o-f color orpaint` on its surface. The lower part or under surface of the color boxshouldbe always elevated far enough above the upper surface of lthetable A to never interfere with the clozth1 riage. Suchrotation shouldbe so regulated that the Vcoloring surface of the roller should rotatewith the same degree of velocity that the carriage is moved. The objectof this is` to properly apply the oil color or paint `to the printingblocks, without the rotation of the roller being caused by its forwardor back motion and contact of the roller with the printing surfaces.

The machinery by which motion is imparted to the platens and coloringapparatus may be thus described. The main driving Y shaft is seen at G,as extending across the `below the top of its frame.

of the machine, such section being taken just Each of these disks hastwo projections z', Za, extended'respectively from its opposite sides,the axis of one being at one hundred eighty degrees of a circle distancefrom the axis of the other pin. The two inside pins Z, z', operate inconnection with two hook bars Z, Z, which are formed as seen in thedrawings, and made to turn vertically on a cross bar or shaft m, thatconnects the vibrating bars The other two projections Zc, Za, act inconnection with the hook bars p, p, similar to the bars Z, Z, andsimilarly connected with the shaft m, the said hook bars p, p, beingformed and arranged as seen in the drawings, and made respectively torest on and be pressed upward by two springs g, g. The coloring carriageis connected with the upper ends of the vibrating bars n, o, byconnecting bars 1yr, which are jointed both to the carriage andvibrating bars in such manner as to allow the vibrating bars andcarriage to simultaneously move backward and forward, the vibrating barsor levers turning on fulcra s, s.

Each of the hook bars Z, Z, p, p, has a bend in it, or is formed as seenat t, the object of such bend being to enable the projection of any onehook bar to pass by such bar while it is in rotation and the projectionof the ybar on the opposite side of its disk is acting on the hook ornotch of its own hook bar. During one half a rotation of the shaft O,the color carriage will be run in or under and beyond the printingplaten (imparting color to the blocksin the meantime), where or'in whichposition it will remain stationary during the next half a rotation inwhich latter time or second half rotation the two platens aresimultaneously made to descend, perform their respect-ive offices andrise upward. During the succeeding or thirdhalf rotation of the shaft O,the coloring carriage will be moved back in an opposite direction so asto ypass under and beyond the printing platen and impart color to theprinting blocks or surfaces. It will remain in this position during thesucceeding or fourth half revolution of the shaft O, in which time theplatens again descend, perform their offices and ascend again. In thismanner the operations of coloring the printing blocks are effected.

The platens are depressed and elevated by Vmechanism which may be thusexplained. Near each end of each shaft O, P, one of four arms a, u, u,u, is attached to and made to project from the shaft as seen in thedrawings. Each of these arms has a projection fu, extended outward atright angles from it and formed as seen in Figs. 2 and 8. Each of theseprojections operates in connection with a roller rw, which is attachedto the platen frame and rests on'the periphery of one of four cams ai,aixed to the shafts O, P, and formed as seen in the drawings.V By'm'eansof each cam and theY projection of the adjacent arm, the platen iselevated' and depressed during the entire rotation of the shafts O, P.

The next portion of the mechanism to be described is that for holdingand moving the sheet of cloth to be printed. Such mechanism may be thusexplained. R, and S are two bars or carriages which are placed as seenin the drawings and properly supported so as to be capable of beingmoved longitudinally with a reciprocating, intermittent motion. Theyareseen in Fig. 8 which is a transverse section of the upper part of themachine. A metallic lip g/ is fastened to the top surface of each of thebars, the bar being cut away under said lip so as to vform a long groovee, for the selvage edge of the cloth to lie in. A series of bent leversa, a, a', is arranged within each bar R', S, and respectively turn onfulcra b', Z9', Z2', as seen in Figs. 5 and 8, also in Fig. 9 whichydenotes a cross section of the bar and the horizontal arm of one ofthese levers. When the horizontal arm of one of these levers is elevatedits outer end is brought up against the under surface of the cloth andin connection with the lip plate y grips it fast. The lower ends of theseveral vertical arms of each set of the bent levers a', a, a, arejointed to one of two long horizontal bars c, c', which by a connectingrod CZ is con- ,nected to one of two vibrating levers e', e', which arearranged and turn on fulcra f, f I as seen in the drawings. These leversare connected together by a cross shaft g, to 1which two connectingpitman rods or bars h, ZL', are jointed, the said bars being also`jointed to two crank disks or plates Z, z". These crank plates are xedon a horizontal and transverse shaft'c, that is put in motion by twospur gears Z, m', the former of which is fixed on the shaft Z0', whilethel latter is fixed on the shaft P.

There is a small stud n', extending inward izo from the outer end of thehorizontal arm From the above it will be seen that when the bars R', S,are drawn forward, the gripping levers are caused to so confine to thebars, the cloth to be printed that it will be moved or carried forwardwith and by them. The impulsion of the bars in an opposite directionwill instantly release the cloth from the grippers, or will depress thehorizontal arms of the gripper levers so as to effect such release. Thecloth will therefore rest still while the grippers are moved back. Eachforward movement of the cloth takes it. far enough to carry under theplaten C, the last imprint made, while it also takes a fresh portion ofthe cloth under the printing blocks or surfacesto be printed by them.

There may be` an7 number of printing platens to one or more compressingor stamping ones, the mechanism being made to print the colors on thecloth and afterward stamp them down and spread them so as to cover theintervals or spaces left between them as herein before described.

. What I claim as my invention is as follows; that is to say, Iclaim- 1. The arrangement of the printing mechanism, the stamping downmechanism, and the mechanism for advancing the piece or strip of clothor of material to be printed and pressed or stamped, such arrangementbeing as exhibited in the drawings, and as above described.

2. And I also claim the combination of the lip bar or plate y, theseries of bent levers a, a', &c., the slide bar R', or S, and the bar o,as made and operated substantially in mannerV and for the purpose ofseizing the selvage edge of the cloth and moving the piece as described.

3. And I also claim the combination of mechanism for operating thecoloring carriage, or imparting to it its back and forth movements andnecessary intervals of rest, the said combination consisting of therotating shaft O, with its circular disks Q, R, and their projectionsz', la, the four hook bars Z, l, p, 27, together with the vibrating barsn, o, as applied together and operated substantially as specied.

In testimony whereof I have hereto set my signature, this seventh day ofOctober A. D.
